Arsenal manager Arsene Wenger has written to the family of missing Derryman Jack Glenn to express his "sincere condolences".

The 23-year-old has been missing since February 2 when he was seen entering the River Foyle.

The Northern Irishman was a devout Arsenal fan, and a campaign titled '#GetJackBack' had been launched to find him again.

Writing to the Glenn family on February 10, Wenger said: "It was with great sadness that we learned recently of the death of Jack and on behalf of all of us at Arsenal Football Club, I do extend to your our very sincere condolences.

"Although I did not have the privilege of knowing Jack personally, I am aware that he enthusiastically followed the fortunes of his team, and for this we are extremely grateful.

"I know that words mean so little at times such as these, but I do wish you to know that our thoughts are with you at this very sad and difficult time."

Jack's sister Katie spoke to the Belfast Telegraph earlier in the month about her brother's sporting connection, and paid tribute to her brother.

"Jack was so sporty, so talented at everything he put his hand to, he was amazing," she said on February 5.

"He was my brother and my best friend."

Jack was last seen wearing a blue hooded sweatshirt, dark tracksuit bottoms and blue trainers.
